Deadeye LA end game

U prob have no energy shield. On my de ice shot i think i have around 12k and 30k ehp. Right now on my Whunter just white mobs when they hit me they take 4k out of my spectral ward that is a sort of energy shield with 84 percent dodge chance. Get the nodes that give evasion per es on helm and es per evasion on body armor

Considering you are level 70 you are very early endgame. 1.5k HP and 5900 DPS lightning arrow is fine for tier 1 waystones but you are going to want better gear to go further. There are some questions you have to answer. Are your resistances capped? This is the most important thing to do as even at 50% resistance you are taking twice as much damage as what you would take at 75% resistance. The other thing is that going pure evasion is not very good. You are going to want to go hybrid evasion and energy shield. Subterfuge Mask on the talent tree with a pure energy shield helmet is a great way to get a ton of energy shield. If you paste your POB people can help you out more.

Link your poe.ninja. go to website sign in to your account copy link to character. You will get much more useful advice that way. For the record 1.5k hp is low for endgame without lots of other defense layers. The obvious stuff is resistances and more energy shield on top of your hp. Are all your ele resistances at 75%?

As other commenter said - check poe.ninja for how other players play the same build as yours. If you get killed, you may have low resistances or evasion.

Also, 5900 dps doesn't seem like much - your bow may be not optimal, maybe you lack some important passive nodes or support gems. The best way is to check poe ninja and import your build into Path of Building.

Since you are level 70, it is better to look for the characters with the level close to yours (70 - 80 is probably the lowest levels now). Look for the high dps characters that don't have expensive endgame uniques, and you will be able to figure out what are you lacking.
